Xfinity Mobile now in Collections

In 2022, I set up new service in my home. At the time, my phone was too old to run on the wifi.  I was offered as a diamond member to recieve a free phone and switch my three phones and one watch over to Xfinity. The representative said "lets start with your other phones and watch." I did that, by the time she got to my phone (the only person that actually needed a phone) she told me I had reached my credit limit and could only buy my "free" phone out. It was outright deceptive. I told her to cancel EVERYTHING. I called to complain, as I felt she knew that the activation of three phone would result in me having to purchase what was supposed to be free. Now, not only am I banned from Xfinity mobile service I never used, but I am getting calls and emails to settle a debt I never incurred.  I am frustrated, I am tired of being routed to call centers in other countries that just tell you whatever with zero accountability. I wanted to consolidate my cable and phone together, and I cant. I have been with Comcast since the remote control was attached to the TV on a 20 ft cord. Please help
